The seal stone comes from an untouched shaft grave near the ancient palace of Pylos. The grave was discovered in May 2015 by Jack L. Davis and Sharon R. Stocker, archaeologists at the University of Cincinnati who had been digging at Pylos for more than 25 years.
“It was after cleaning, during the process of drawing and photography, that our excitement slowly rose as we gradually came to realize that we had unearthed a masterpiece,” they wrote in the journal Hesperia.
The seal stone presents two mysteries. One is how and why it was engraved in such detail. The other is whether its battle scene, strongly evocative of those in Homer’s “Iliad” and “Odyssey,” depicts an event that contributed to the oral tradition behind the works of Homer.
The seal stone’s owner, known as the Griffin Warrior after the mythical animal depicted in his grave, was buried around 1450 B.C. He lived at a critical period when the Minoan civilization of Crete was being transferred to cities of the Greek mainland.
Local chieftains, as the Griffin Warrior may have been, used precious items from Crete to advertise their membership in the Greek-speaking elite of the incipient Mycenaean civilization, the first on mainland Europe. Their descendants, a century or so later, built the great palaces at Pylos, Mycenae and Tiryns, places mentioned by Homer.
Dr. Davis and Dr. Stocker believe that the seal stone, like other objects in the Griffin Warrior’s grave, was made on Crete. Work of such quality was not being produced anywhere on the Greek mainland at the time. The detail is so fine that it seems the engraver would have needed a magnifying glass, as would admirers of his work.
Yet no magnifying implements have been found on Crete from this era. Perhaps the engraver was nearsighted, the two archaeologists suggest.
Fritz Blakolmer, an expert on Aegean art at the University of Vienna, argues that the seal stone is a miniature copy of a much larger original, probably a stucco-embellished wall painting like those found at the Palace of Knossos on Crete. He said the seal must have been engraved by someone with a magnifying glass, even though none has been found, and dismissed the possibility that people of that era had sharper eyesight than today.
The seal, carved on a hard stone known as agate, shows a victorious hero slaying an adversary while a third warrior lies dead in the foreground. The seal stone is mounted so that it can be worn on the wrist, and indeed the hero is wearing just such an item, as if it were a wristwatch.
The two defeated warriors seem to belong to the same group, because both are wearing patterned kilts whereas the hero sports a codpiece. The scene evidently represents some event that would have been familiar to the Minoans who made the seal stone and to the Griffin Warrior’s community.
The seal stone’s possible relevance to the Homeric epics is intriguing but elusive. Early archaeologists, such as Heinrich Schliemann, who first excavated Troy and Mycenae, believed the “Iliad” recounted historical events and were quick to see proof of this in the artifacts they found.
Later archaeologists were more doubtful, but allowed that the destruction of Troy in 1200 B.C. could have been remembered in oral poetry for 500 years until the Homeric poems were first written down, around 700 B.C.
The Griffin Warrior was buried around 1450 B.C., distancing him even further from the first written version of Homer. Still, there is some evidence that the oral tradition behind the Homeric epics traces as far back as Linear B, the first Greek writing system.
Linear B was adapted by the Mycenaean Greeks from Linear A, used by the Minoans. The oldest known Linear B inscriptions date to 1450 B.C., and the script disappeared after the collapse of Mycenaean civilization around 1200 B.C.
Some of the scansion problems in the Homeric poems “can be resolved if you restore older forms of Greek which are consistent with the dialect recorded in Linear B documents,” said Dr. Bennet of the British School at Athens.
So the oral tradition that led to the Homeric epics perhaps stretched over seven centuries.
“We’re not saying this is a representation from Homer,” Dr. Stocker said of the tableau on the seal stone, while admitting it would be “fun to believe” the hero is Achilles. Rather, the image “is part of a cycle of stories familiar to both Mycenaeans and Minoans.”
Dr. Blakolmer, too, finds it tempting to see the figures on the seal as Homeric heroes, like Hector or Nestor, but in his view the temptation must be resisted.
“Fifty years ago, you would find nice attributions to Homeric heroes, but today’s academics are very careful in their Homeric attributions,” he said. “We have to make our own mistakes, not theirs.”
